Connecting the 3-axis Servo Module

Wiring a Probe to Multiple Servo Modules
Systems with more than one servo module should have their touch probe
connections tied together in parallel. This allows the position to be latched
on all servo modules at the same time with the same input. Only one
power connection needs to be made (with pull up or down resistor). The
other probe connections should be made in parallel on all servo cards.
Figure 4B.26 shows a typical wiring diagram for multiple servo cards.
